Fendi Uomo EDT vs EDP

I was at Marshalls today and noticed they had Fendi Uomo EDP on the shelf. I have the EDT but it has never lived up to the promise made by the sample vial given to me in college by a [beautiful] friend. I still have the sample and have confirmed that it's the better version I remember.

Since it's only $20, I'm tempted to just dive in and get the EDP. But I'd like to hear if anyone has opinions on the differences between these two.

Also I picked up Guerlain Vetiver, Van Cleef & Arpels Pour Homme and Opium (for my wife) this weekend so I'm feeling kind of poor right now and I'd rather not purchase a duplicate unnecessarily...
